Hallo FME enthusiast,

I am trying to create a 2D overview map from 3D roofs (OuterEaves).

What is the goal?
The goal is to create a 2D view map from the top and those areas below should show the area in 2D, which seen are from the top and the highest Areas should stay on top.

What attributes do I have for the roof surfaces?
-ID of the building
-xyz coordinates of the OuterEaves

But I fail because of the intersection of the roof surfaces. The 3D data set is not 100% cleanly created and therefore I have up to 10 overlaps of the roof surfaces to each other or even within themselves.
My question to you: What is the easiest way to clean up these overlaps in 3D space so that I get my result?

King regards,

Michael
